Founder of BillingBase, a non-custodial stablecoin billing product. Owned product vision, customer development, and design end to end; directed a small team on implementation. Defined the product from the ground up and ran user discovery interviews with prospective merchants and translated their pain points into the product roadmap. Designed the system, including a risk service spec covering behavioural analysis, AML screening, wallet scoring, and fraud detection for sensitive customer financial data. Scoped PayLinks, a no-code feature letting non-technical merchants collect stablecoin payments without API integration. Drove go-to-market and worked directly with early customers throughout.
